1. Calculate GDP using the following information (where there is no government and no foreign trade.

C = consumption

I = Investment

Y = GDP

C = 100 + 0.8Y

I = 1000

answer

Y = 1000 + 100+ 0.8Y

Y – 0.8Y = 1000+100

Y – 0.8Y = 1100

0.2Y = 1100

Y = 5500

2. How will the answer change if I increases to a) 2000

b) 4000

c) 10000

3. If investment is now back to 1000 and the consumption function isC = -200 + 0.9Y

What is the GDP now?

4. What do you think are likely to be the main determinants of investment by firms?5. Is it likely that individual consumer’s marginal propensity to consume will vary with the age of the consumer? If so how will it vary?

6. Explain how the equilibrium in the circular flow will be restored if there were a fall in investment.

7. For what reasons might GDP be a poor indicator of the level of development of a country and its rate of economic development?

8. Why might one country experience faster rates of economic growth than another?9. How would you derive a figure for household disposable income when starting from the GDP figure?

10. Explain how GDP at factor cost can be calculated using the expenditure method.
